AIR-FORCING MEANS FOR A GAS-GENERATOR.

To all whom it may concern:

Be it known that we,'GEo1iGE P. CAMP- BELL and FRANK I-I. RINGEMANN, citizens of the United States .of America, and residents of Cincinnati, county of Hamilton, State of Ohio, have invented certain ynew and useful Improvements in AireForcing Means for a Gas-Generator, of which the following is a specification.

The object of our invention is a generator which will manufacture gas automatically at a rate that is in direct proportion to the rate at which the gas is being utilized at any time and in which the gas produced is uni l5 form in character.

In the accompanying drawings Figure 1 is a longitudinal sectionalview taken through the apparatus embodying our invention. Fig. 2 is an enlarged view of the valve for :o regulating the supply of water for actuating the air tank, showing it in the position it occupies when water is being supplied to raise the piston of the air tank.` Fig. 3 is a similar view, but showing the parts in the 25 position they occupy after the iston has been raised, showing the supply o water cutv off from the tank and the same opened to the discharge. A

Inour generator the gas is produced by iquid carr f ing the air laden with vapor to a gas tank, from which the gas may be drawn in quantities as desired. an airreservoir, in which the air is stored sure being reg in the gas tank.

The air reservoir consists of a lower cylindrical vessel, A, having a bottom, a, and Surrounding the vessel, A, is a similar cylindrical vessel, A', which at fits upper end has brackets', c2, which sup-port vertical standards, a3, which Vare connected together at their upper ends by a spider, a4.

ated by the quantity of gas 454Over vessel, A, an inverted cylindrical vessel, B, is iitted to slide, whose end, b, is

closed and carries journal wheels, t, to en.

gage the rods, c3, to steady the vessel, -B, in its reciprocation. Vessel, A, has a central Within which slides a piston, C, the piston being connected by a piston rod, c, with the top, b, of the vessel,-B. The piston is actuated by water from the pipe, c. Tank, A, has passing valve casing, c5, within Specifcaton'of Letters Patent.

which is a gravity valve, a, which is raised by the atmospheric pressure when the vessel, B, is carried upward to` admit air into the air reservoir, and which closes when the vessel, B, is descending to force the air out through pipe, 0.7, to the fluid tank, D. In passing from the air reservoir to the fluid tank, the air goes through an air filter, d, to be cleansed from impurities. From the air filter the air passes through a i e, d', to the bottom of the fluid tank, whiclii lilas a funnel, d2, for spreading the air to 'lpass it upward through the fluid tank, D. he fiuid is Supplied from a pi e, d3, which has at its lower end av valve, di, controlled by a float, d5, which opens the valve to allow fluid to pass into the 'Huid tank, D, whenever the iiuid has fallen below a certain point, and closes the valve again when the Huid has risen to a certain point. The air after having passed through the fluid into the top of the tank, D, charged with the vapors, passes through a pipe, d, raising valve, e, and into the gas reservoir, which consists of a lower cylindrical vessel, E, closed at its bottom, e', surrounded by a similar vessel, E', and an upper cylindrical vessel, E2, closed at its upper end, c2, and fitting snugly over the vessel, E. Vessel, E, carries standards, e3, which are :engaged by wheels, e4, upon the upper end of vessel, E2. p

. We will now describe the means by which the supply of water for raising the tank, B, for charging the air reservoir is cut otf from the same, and the Water in the casing, at, is discharged. Located in'the water supply pipe, c', is a valve, F, Whose casing has a central ,horizontal diaphragm, f, in which is formed a valve seat. Below the diaphragm, f, is a Wa f leading to the discharge, which is contro led by a valvag, seating upward against a valve seat, ff, y a coiled spring, f.. Upon the side o the valve is a channel, j, leading into the casin et. Valve, f2,

as a valve stem, f6, upon wiich above diaphragm, f, is located a valve, j?, and which terminates in a piston head, f5. When valve, f7, is seated against the diaphragm, f, to close off communication between the Water supply pipe, c and the casing, c", the valve, fl, 1s carried downward from its seat to open the communication-between thedischarge, f', and the casing, at. The means lby which the piston head, ji), is actuated to open the casing, a, to the discharge opening G, which carries at its outerend a weight, g,

and an outwardly projecting arm, g, whic carries at its outer end a pin,'g2. The arm, G, at itsinner end, g3, is bifurcated and between the bifurcated ends a rod, H, is pivoted upon a pivot pin, g4, and at its outer end the rod, H, is coupled to the piston head,

f8. The arm, g', is connected by means of a chain, g5, with a journal rod, M, which is connected`to the tank, B. Rod, M, carries at its lower end a cam shaped arm, m, in whosev path the pin, '92, stands when the arm, G,

as been`carried to position shown in Fig. 3. When the vessel, B, is carried upward, the chain, g5, rotates the arm, G, upward around the pivot, g4. After the arm, G, in its upward motion has passed the vertical position, the weight, g, carries it downward and causes the arm, G, to strike the piston head, f8, as shown in Fig. 3, and to carry valve stein,

downward, closing the valve, f7, against t 1e diaphragm, f, and opening the valve, f2, to allow the water to discharge from the casing, a4. The weight of the vessel, B, which may be supplied with weights to the amount desired, then carries it downward. On its 'downward movement the arm, m, contacts the pin, g2, forces the arm, G, back to the position shown in Fig. 2, at which time the spring, f4, carries the valve `rod, f, u ward, c oses the valve, f2, and carries the va ve, f7, upward, opening the communication between the water supply c, and the casing, a4, so that water may be again admitted to it to raise the piston, C.

The means by which the supply of water to' the pipe, c, is regulated, is as follows: Located 1n the sup ly pipe, c, is an ordinary two way valve, lit, which is connected to a rod, r, which is pivoted to a link, r', whose outer end is connected by a chain, r2, to the top of vessel, E2. When the vessel, E2, is carried to the upper limit of its travel by the pressure of gas from the tank, D, rod, 1", is rotated, closing valve, R, and cuts off the supply of water to the pipe, c. The vessel E2, is lowered bydrawmg off gasfrorm the gas reservoir, the rod, r, is rotated downf eeaeee wardly, opening up valve, R, to supply water to the pipe, c

In operation it is seen that since the vessel, B, cuts off the pressure of the water after the vessel has reached a predetermined height, the pressure of the air in the air reservoir never exceeds that of the weight of the vessel, and therefore the force with which the air is carried through thelvolatile fluid is uniform and the character of the gas will be likewise uniform. It is likewise obvious that the generator is automatic in its action throughout, that as the supply of gas is drawn off, from the 'gas reservoir, it actuates the water valve which admits water to' the airreservoir to raise the same to supply more air to the volatile fluid and thereby to generate more gas to take the place of that being utilized.

What we claim is:

An air forcing means consisting of a stationary vessel closed at its lower end and open at its upper end and a second vessel open at its lower end and closed at its upper end and telescoping into the lower vessel in combination with a piston cylinder, a piston within the cylinder whose reciprocation actuates the movable vessel of the air reservoir, a water supply pipe for admitting water under pressure to the piston cylinder for actuating the piston and a valve for regulating the supply of water to the piston cylinder consisting of aI valve casing having a discharge opening and a channel leading into the piston cylinder, a valve for regulating the opening and closing of the channel and the opening and closing of the discharge, whose valve stem extends beyond its valve casing, an arm pivoted adjacent to the water valve and carrying a weight at its outer end, means for coupling it to the upper vessel of the air reservoir whereby 'the raising ofthe vessel throws the arm in contact with the valve stern actuating it to open the discharge and close off the supply of water to the iston cylinder and the lowering of the vesse actuates the arm to close the discharge and open the supply to the piston cylinder, substantially as shown and described.
